Researchers have developed RESample, a novel data augmentation framework designed to improve the performance of Vision-Language-Action (VLA) models in robotic manipulation tasks. This framework addresses the issue of distributional shift and failure recovery by actively supplementing existing datasets with trajectories that include failure modes and subsequent recovery actions. By training a coverage function to identify missing failure cases within the data distribution, RESample guides exploratory sampling to generate these critical trajectories. Experiments on the LIBERO benchmark and real-world robotic tasks demonstrated that RESample significantly enhances policy success rates, achieving up to a 12% absolute gain with a modest increase in training data.
